Similar "Lie Detector" skill as Columbo
This show has been compared to Columbo for the reverse-WhoDunnit, HowCatchUm format, and also the modest, quirky styles of Columbo & Charlie.
I think Columbo has similar "lie detection" skills as Charlie, though it's not presented so outwardly as a "special talent" or superpower. But I think that's how he's able to hone in on the suspect right from the beginning.
